Abstract

In this paper, we would like to point out some similarities of interesting structures of Fučík spectra for continuous and discrete operators. We propose a simple algorithm that allows us to complete the reconstruction of the Fučík spectrum in the case of small order matrices. Finally, we point out some properties of the Fučík spectrum in general unifying terms and concepts.

Notes

  1. 1.

    There are more than 300 qualitatively different patterns of the Fučík spectrum for 3 × 3 matrices (cf. the simple situation of 2 × 2 matrices in Fig. 4).

  2. 2.

    Let us note that examples in Sect. 2 are treated in H = L 2(0,π) ordered by \(K =\{ u \in H:\ u = u(x) \geq 0\ \ \mbox{ a.e. }x \in (0,\pi )\}\), and examples in Sect. 3 are treated in \(H = {\mathbb{R}}^{n}\) ordered by \(K = {(\mathbb{R}_{+})}^{n}\).
